A vehicle powertrain proactive damping system includes a plurality of proactive damping structures mounted on a powertrain structure with each proactive damping structure includes a magneto rheological elastomer (MRE). An electromagnet is associated with each proactive damping structure. A control unit includes a processor circuit. A sensor obtains vibration data regarding the powertrain structure. A LIDAR sensor is mounted on the vehicle and is electrically connected with the control unit. The LIDAR sensor provides data to the control unit indicative of upcoming road surface conditions to be experienced by the vehicle. Based on data from at the sensor and the LIDAR sensor, the processor circuit is constructed and arranged to control voltage to the electromagnets to selectively adjust a rigidity of the associated proactive damping structure so as to control vibrational effects on the powertrain structure.

A suspension control device including an electrorheological damper, a high voltage output circuit, a connection portion, and a control unit. The electrorheological damper includes a cylinder sealingly containing electrorheological fluid, a piston, a piston rod, and a positive electrode provided in a portion through which a flow of the electrorheological fluid is generated by a slide of the piston in the cylinder, and configured to apply a voltage to the electrorheological fluid. The connection portion includes an electrode connection portion configured to connect the high voltage output circuit and the positive electrode to each other, and a ground connection portion configured to connect the cylinder and a ground to each other. A resistor member, which has a resistance value set to a load resistance value of the electrorheological fluid in a regular-use temperature range of the electrorheological damper, is provided between the electrode connection portion and the ground connection portion.
